SELFJNKING HAN-D STAMP.

Application ilediMay 13, 1924. Serial No. 713,060;

To all whom it may concern:

Be it known that--LFREDERICII CHILDS, a citizen ofthe Dominion of Canada, and

a resident of San Francisco, county of San Francisco, State of California, have invented a new andi useful ,Self-InkingHand.

Stamp, of which the following is a specification.

The present inventionrelates to improvements in self-inking hand stamps and has particular reference to hand stamps now commonly used in which a plurality of ribbons having characters molded thereon are mounted in parallel relation so as to pass over the bottom of a supporting structure and to present characters in a desired order at the bottom face for stamping purposes.

The principal object of the present invention is to provide in connection with a hand stamp of such simple construction an inking pad that will automatically resume its place opposite the bottom face and that may be readily removed by a slight pressure on an element projecting from the handle when it is desired to use the device. Further objects and advantages of my invention will appear as the specification proceeds.

rl`he preferred form of the invention is illustrated in the accompanying drawing, in which Figure 1 shows a front view of my improved stamp, Figure 2 a. vertical section through the same taken along line II-II of Figure 1, and Figure 3 a similar section showing my inking pad swung sideways so as to clear the bottom face of the stamp. lVliile I have shown only the preferred form of the invention, I wish to have it understood that various changes or modi tications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

The stamping device shown in the drawing is substantially of conventional construction and includes two side plates (1) connected by a top element (2) and a bottom element (3) in suoli a manner as to present a substantially rectangular retainer for the working mechanism of the stamp, the side elements being preferably tapered so as to narrow down toward the bottom to a width corresponding to the height of the characters to be used.

Mounted in the upper portion of the frame is a shaft (4) on which are rotatably disposed plurality of drums (6) having flanges (7) thereonby means of'iwhich they may be manipulated.

-have various characters printed or molded thereon so that various combinations orf characters may be assembled atthe bottom face. A handle (9)y extendsupwardly from thetop plate No noveltyv is vclaimed for the device thus fardescribed.

An inking pad (11) made to fit the bottom face of the exposed ribbons is provided with arms (12) extending from the ends thereof which straddle the sides of the frame and are pivoted to the same as shown at (13) near the edges thereof. The arms, which are substantially of the -sa-me width as the sides of the frame, are formed with slanting slots (14) near the upper edges thereof.

A yoke (16) mounted for vertical reciproeating motion has ins (17) extending from the extremities tiereof which pins are adapted to ride in slots (14). The connect-- ing member (18) of the yoke rides in vertical slots (19) in the sides and has extending upwardly therefrom, slightly offset, the rod (21) extending through the handle (9) and formed integral with a cap (22) which latter is also slidable in a vertical perforation (23) in the handle (9).

A spring (24) disposed between the cap (22) and the top face (2) of the frame tends to project the cap upwardly and to thereby swing the pad (11) into an operative position relative to the bottom characters.

The device is manipulated as follows:

Ordinarily it will lie on the desk ready for use with the inking pad in an operative position. When it is to be used the operator lifts it from the desk, depresses the cap (22) and applies the stamp. The depressing of the cap (22) forces the yoke (16) downwardly over the opposition of the spring 24) and causes the pins (17) to ride in the slots (14) while simultaneously swinging the arms (12) about the pivot (13). The pad is thus temporarily made to clear the bottom face of the stamp until the stamp has been used, whereupon the operator may just place it back on the desk, when the spring will automatically return the Vpad to its operative position.

I claim:

1. In a hand stamp of the character described, a substantially rectangular frame.,

Endless ribbons (8) pass .over the drumsl and the bottom plate inparallel'relation to one another and aV shaft mounted parallel to the bottom thereof, drums mounted on the shaft, endless ribbons encircling the drums and the bottom element of the frame having characters thereon adapted to be presented downwardly in selected combinations, an inking pad bons encircling the drums and the bottom element of the frame having characters thereon adapted to be presented downwardly in selected combinations, an inking pad adapted for engagement with the downwardly presented characters having arms extending therefrom adapted to straddle the side elements of the frame and pivoted thereto near one edge thereof, a push button in the top of the handle and a set of rods operatively associated therewith having pins eX- tending therefrom riding in slanting slots in the arms'for swinging the same about their pivots when the push button is depressed so as to swing the inking pad into an inactive position.
